However one item that has drawn some attention over the years is the collective group of silicates.

This hobby has been dominated by white lights with blue actinics for years. Recently I covered the topic of using green light to get more fluorescence out of your corals (http://reefbuilders.com/2010/04/06/g...orescence-red/). Now, we bring you the topic of using red light to increase reflective coloration.
